My invention consists in a new and useful improvement in oil conduits and is designed to provide a device to be used in connection with the crankcase of an internal combustion engine to facilitate the charging of the crankcase with lubricating oil. It has now become a very general practice for lubricating oil to be dispensed in sealed containers, and my improved device is designed for use in connection with the. ordinary l0 form of sealed can in which the oil is packaged for sale. cutting the can to permit the oil to ow there-r from, and this blade is provided upon the end of the conduit so that the oil ows directly from the can, through the conduit, into the crankcase. My device is also designed so that, if desired, the oil may be poured into the conduit by any of the ordinary methods which have .been used before the use of the sealed containers. Thus I have` provided a conduit for the oil, to be permanently attached to the crankcase, and through which the oil may be supplied to the crankcase from either a sealed or an open container. The particularly novel features of my improved device are the rupturing means for opening the sealed cans, the reception means forV oil poured from open containers, and the provision for the usual breather construction in connection with the intake of the crankcase.

While I have illustrated in the drawings filed herewith and have hereinafter fully described two specific embodiments of my invention, it is to be distinctly understood that I do not consider my invention limited to said specific embodiments, but refer for its scope to the claims appended hereto.

In the drawings:

Fig. 1 is a side elevation of the device.

Fig. 2 is a vertical section of the device, showing its cap removed and a can on the device.

Fig. 3 is a horizontal section on the line 3-3 of Fig. 1.

Fig. 4 is a side elevation, partly in section, of a modified form of my device.

Fig. 5 is a vertical section of the modified form,

showing the cap removed and a can on the device.

Fig. 6 is a horizontal section on line 6-6 of Fig. 4.

As illustrated in Figs. 1, 2 and 3 of the drawings, my device is provided at its bottom with the tubular portion I of sufficient diameter to surround the open end of the intake pipe 2 of the crankcase, forming a peripheral channel 3 thereabout. The portion I is provided with a My device has a rupturing blade for v modified form of my device comprising a conical series of bosses 4 through which are tapped bolts 5 for attaching the device to the pipe 2, as clearly indicated in Figs. 2 and 3. Extending upwardly from the portion I and at an angle of 45 is the tubular portion 5 on which is co-axially `5 mounted the bowl 'I having on its upper edge theperipheral bead 8. Mounted in the center of the bowl 'I is the conduit 9 which extends to a point above the bead 8 and downwardly through the portions 5 and I, its lower open end II] bel0 ing extended into the pipe 2 when the device is mounted thereon. The upper end of the pipe 9 is formed to provide a rupturing blade II. A series of holes I2 are provided in the pipe 9 at points adjacent to the bottom of the bowl 1, to 15 afford communication between the bowl 'I and the pipe 9. I provide a suitable cap I3 for covering the bowl l when my device is not in use. This cap I3 is suii'iciently long as to extend above the upper end of the pipe 9, and has its skirt I4 20 of sulicient diameter to afford a peripheral channel I5 about the upper edge of the bowl 1. The cap I3 is provided atA points adjacent this skirt I4 with spring fingers I6 adapted to co-act with the bead 8 of the bowl 1 to fasten the cap I3 25 thereon.

As clearly illustrated in Fig. 2, the can C containing the oil to be placed in the crankcase through the inlet pipe 2 is forced down against the rupturing blade II on the upper end of the 30 pipe 9, thus causing the pipe 9 to enter the can C and permit the oil to drain from the can C through the pipe 9 and pipe 2 into the crankcase, the bottom of the can C resting on the upper edge of the bowl 1. It is obvious that the 35 rupturing of the can C by the blade I I will cause such a torn opening in the wall of the can C that some of the oil may escape, about the pipe 9, into the bowl 'I and will drain therefrom through the holes I2 into the pipe 9. In this way also the residue of the oil in can C, when the oil level has reached the level of the upper end of the pipe 9, will drain, completely emptying the can C.

Figs. 4, 5 and 6 of the drawings illustrate a element 2l provided at its base with threaded 45 orifices 22 for the reception of bolts 23 passed through bolt holes in the intake pipe 24 of the crankcase 25,'by which the element 2| is fixed in the pipe 24. The element 2| has at its peak a 50 tubular portion 26 provided with a rupturing blade 21. The conical element 2l has a plurality of orifices 28 and 28', the latter being positioned closely adjacent the point of juncture of the base of element 2I and pipe 24. As illus- 55 trated in Fig. 4, it is obvious that when the element 2l is mounted in the pipe 24', the ordinary type of breather cap 29 may be applied to the pipe 24. As illustrated in Fig. 5, it will be ob vious that when can C is forced down on blade 21 it will be ruptured to allow the oil to flow through tubular element 26, conical element 2| and pipe 24 into the crankcase 25, the can C' resting upon the upper end of the pipe 24.

It will be noted that in the `form of my device illustrated in Figs. 1, v2 and k3 there vis provided the breather construction by the channel 3 provided between portion l and intake pipe 2, and also by the channel l5 about the bezel 8 of the bowl 'l when the cap I3 is applied thereto. In the modied form of the device illustrated in Figs. 4, 5 and 6, the ordinary breather cap 29 is used.

It will be obvious that in both forms of the device the orices l2 and 28, 28 respectively are provided so that when oil is poured from an open container it will pass through said orifices into the crankcase. These vorices 'I2 and 28, 28' also serve to admit air to facilitate Vthe ow-of the oil through the conduit when a sealed container supplies the oil.`

Having described my invention, what I claim I. In an oil conduit for the ol intake pipe of an internal combustion engine, the combination of a pipe having its upper end provided with l a rupturing blade; and `tubular means on said pipe and provided with means adapted to attach the pipe to theoil intake pipe, said tubular ing to said crankcase and provided on its outer end with a rupturing blade, and surrounded by a bowl, a series of orifices being provided in said conduit adjacent the bottom of said bowl, and

said bowl being provided with a depending pipe surrounding lsaid conduit and provided with means .adapted to mount said pipe upon the crank case.

4. In an oil conduit for the crankcase of an internal combustion engine, ithe combination of a tubular casing to be positioned about the intake :pipe of the crankcase and afford ia peripheral airspace vbetween said pipe and Said casing, and yhaving clamping Ameans to attachA the casing to the pipe; a vbowl mounted on saidcasing; and a vpipe mounted in said bowl and passing through said .bowl and casing, and provided with a 'rupturing `blade on its upper end and a series of orifices adjacent the inner surface of the bowl, and having its lower end disposed within the intake pipe when the casing is clamped thereto.
